Enhancing Adherence by Building Online Communities

The purpose of this study is to determine whether online peer support will increase adherence to an internet-based pedometer walking program.

Stepping Up to Health with eCommunities is a study that takes what we already know about motivating sedentary, chronically ill people to walk, and begins to explore what it takes to keep people motivated to exercise over time: the ability to self-monitor behavior with accurate ecological momentary assessments. We have theorized that peer support, monitoring and competition are ways in which people can stay motivated to meet their walking goals; thus, we have built into this intervention online forums for participants to communicate with each other and garner support, as well as a pilot one-to-many competitive game based on the percent of an individual's goal met. Our research question is whether online community participation can increase adherence to an Internet-mediated walking program, which consists of an uploading pedometer, and going to a website to receive graphical and textual feedback as to whether participants are meeting gradually increasing walking goals. Three hundred participants will spend four months in this randomized, controlled trial to compare the intervention alone to the intervention plus online community support.
